    My hat off to you, what a fantastic project. Sure beats an Airfix kit.

    OK, so progress has slowed a little, I know, I know, I was already moving along like a tortoise! The hold up now is the weather ironically. Up till now I've been working in the relative warmth of my cellar, however, I now need to smooth out the lugs prior to painting and this requires the use of filler and sanding. The filler gives off terrible chemical fumes and the sanding, well, to say it makes a mess would be an understatement, so outside it is.

    I started by stripping the bike back down and sanding and trimming the areas that where fouling the back wheel and chain. With that done, it was on to the first batch of filler.

    Then when it had set it was time for the dust to fly:

    Some areas need more filler than others, but it's slowly coming together. I've applied two coats so far, but there are still small voids and gaps, so I'll need to apply some more. But that needs to wait until the weather has returned above freezing.

    Good job with the filler.

    I've lost track of the aesthetic decisions. Are you painting some, all or none of it? Are you going to paint over the smoothed lugs or do a final neat wrap with the cloth & epoxy?

    :laugh: you and me both!

    So I'd laid an extra coat of resin down after the initial sanding to see how it looked, but I realised that I wouldn't be able to recreate a good enough finish to make me happy.

    So it's back to plan A, which is:

    To smooth out the last of the irregularities in the lugs with filler.

    Paint the Lugs only in British Racing Green, followed by several coats of Lacquer.

    Remove the protective paper from the Bamboo frame tubes. Paint the entire frame in Lacquer.

    Crack open a beer.

    Build the bike up.

    Go on then! Some of us are watching this thread avidly waiting for new episodes :smile:

    On a related note, once you've completed this project (season 1) what are you'r plans for season 2? maybe a Bamboo Tandem or a Recumbent??

    Seriously, it's been great following your progress on here, thanks for sharing your project :smile:

    Well as much as I'd love there to be a season 2, I've a feeling the wife would go mad at me!

    So I've been a little frustrated of late, as much as I've wanted to be marching on with this, the weather has other ideas. As I mentioned in my last post, I'm working outside at the moment due to the dust and fumes generated by the filling and sanding. Frustratingly it's been far to cold to work outside too much. However I have had some odd occasions where I've managed to catch a window of good weather. So far it's been an endless round of sanding, applying more filler, then more sanding. I've used a range of different grades of sandpaper and the end result is really smooth. It's starting to look good and the headstock is 95% finished. The raw Bamboo is still hiding under it's protective paper and waiting for the day the lugs are painted before seeing the light of day again.

    I've also received the paint from spray.bike and bought some primer as well. Again I'll need to wait until Spring properly shows up, because the paint doesn't like to be used in cold temperatures, ideally 15°C would be best. So updates will slow down until Spring decides to finally show up I'm afraid.

    Thanks Joe. I'm determined to not get impatient, though it's hard at times!

    @chriswoody I don't know what happened to my settings, but I have been away from your amazing build for quite some time, the big problem I have now is that my jaw is gaping open so much in utter and complete amazement at what you have created that typing this is proving to be quite difficult !!

    Roll on the warmer weather.

    All the best

  11. I admire your patience. If it was me I'd be slapping on the paint in inappropriate conditions, and getting horrible results.

    Actually, that's not true. If it was me I'd have ballsed the whole thing up long ago.

    Well springs arrived! We've had some glorious weather this last week and thankfully I've also been off work for the Easter break. So in-between household chores and Daddy day care, I've managed to squeeze in some extra bike time.

    Mostly it's been endless rounds of sanding and filler. I'm permanently covered in dust and the fingerprint sensor on my phone no longer responds to my fingerprint, it's so filled in. However, today I finally reached the point where I declared myself ready for the first round of primer. So I masked off the BB, headtube and seat tube.

    Then I set to work with the primer, passing over with light strokes and slowly building up the finish.

    Overall it didn't look to bad. However, as expected it did show up some flaws here and there. So it's back to sanding and filling. Oh the joys!

    The actual end colour will be a fair bit darker, so hopefully the flaws won't stand out so much, but I'll keep working at it. With lighter evenings and warmer weather I'm hoping to progress reasonably quickly now. who knows I may even finish this month?

    That looks really smooth, especially around the head tube.

    Getting there, it's worth putting that extra effort in now, would be a shame to spoil it at the end, have really enjoyed this thread.

    A high build primer will probably fill the majority of the small blemishes - looking good :becool:
